I believe I've figured it out. I must have an old version of 'htmlize' installed somewhere, I 'edebug' traced through the code and fell through to this part: (when lang (if (featurep 'xemacs) (require 'htmlize) (require 'htmlize nil t)) (when (not (fboundp 'htmlize-region-for-paste)) ;; we do not have htmlize.el, or an old version of it (setq lang nil) (message "htmlize.el 1.34 or later is needed for source code formatting"))) I couldn't manage to set up my load-path to load htmlize 'properly' (is htmlize not able to be loaded via 'load-path' and 'require'?), but after downloading htmlize 1.43 and adding the following to my .emacs, I seem to be in business again: (load-file "~/share/emacs/site-lisp/htmlize/htmlize.el") Thanks everyone.
